ADA Parking Lot Requirements in Texas: 2026 Checklist

Accessible parking is the most commonly cited accessibility issue on commercial property, and it is also one of the easiest to fix once you know what you are looking at.

This checklist covers the practical items we verify on every striping job in Texas. It is a working guide, not legal advice, and your architect or a Registered Accessibility Specialist has final say on any specific project.

Which rules apply in Texas

Texas properties are governed by the federal ADA Standards for Accessible Design and by the Texas Accessibility Standards, administered by the Texas Department of Licensing and Regulation. TAS closely tracks the federal standards, with some Texas-specific administrative requirements including review and inspection thresholds for construction projects above a dollar value.

Restriping an existing lot in its existing configuration is generally maintenance. Changing the layout, resurfacing, or altering the accessible route can trigger a requirement to bring accessible elements up to current standards. That distinction catches a lot of owners off guard.

How Many ADA Parking Spaces Are Required?

The required count scales with the total number of parking spaces in the lot. Roughly, the standards require one accessible space for the first 25 total spaces, two up to 50, three up to 75, four up to 100, and then a sliding scale that increases more slowly above that.

Where a site has multiple lots or entrances, spaces generally need to be distributed among them rather than clustered in one place, and they must be on the shortest accessible route to the accessible entrance.

ADA Parking Space Dimensions

This is where compliance quietly slips on Blackland clay. Slopes that were in tolerance when the lot was built can drift out as the soil moves and the pavement settles.

• Car-accessible stall: minimum 96 inches wide, with a minimum 60-inch access aisle.
• Van-accessible stall: 132 inches wide with a 60-inch aisle, or 96 inches wide with a 96-inch aisle.
• Vertical clearance for van routes: 98 inches along the vehicle route, at the space and at the exit.
• Slope in any direction at the space and access aisle: maximum 1:48, roughly 2 percent.
• Access aisles must be marked and connect directly to the accessible route without requiring travel behind parked cars.
• Accessible route running slope: maximum 1:20 without ramp requirements, and cross slope no steeper than 1:48.

Van-Accessible Space Requirements

At least one in every six accessible spaces, rounded up, must be van-accessible. In a small lot with only one accessible space, that space must be van-accessible, which is the single most common miss we find on older Texas properties.

A van-accessible space is either 132 inches wide with a 60-inch access aisle or 96 inches wide with a 96-inch aisle. It also needs 98 inches of vertical clearance along the vehicle route from the entrance to the space and back out, which matters at garages, canopies and drive-through overhangs.

Each van space carries an additional van-accessible designation on its sign. A pavement symbol alone does not satisfy that requirement.

Signage & Striping Requirements

Each accessible space needs a sign displaying the International Symbol of Accessibility, mounted so the bottom of the sign is at least 60 inches above the ground surface, measured so it stays visible when a vehicle is parked there.

Van-accessible spaces need an additional van-accessible designation. Texas also requires specific fine notice signage for accessible parking enforcement, and many cities have their own supplemental requirements worth confirming locally.

Access aisles should be striped and, in most jurisdictions, marked no parking. Pavement symbols alone do not satisfy the sign requirement.

Field checklist

Run this list on every property annually, and after any resurfacing or restriping work.

• Total stall count recounted and accessible count verified against it.
• At least one in six accessible spaces is van-accessible.
• Stall and aisle widths measured, not assumed.
• Slopes checked with a level at multiple points in each stall and aisle.
• Signs present, correct type, mounted at least 60 inches to the bottom.
• Accessible route from stalls to entrance is continuous, unobstructed and correctly sloped.
• Curb ramps present where the route crosses a curb, with compliant slopes and detectable warnings.
• Markings legible, not faded, and access aisles clearly striped.
• No drainage grates, ponding or pavement failures within the accessible route.

Fixing what you find

Signage and striping issues are inexpensive and can usually be corrected in a single night. Slope problems are pavement work, requiring grinding, leveling or localized reconstruction, and they need to be scoped properly.

We include an accessibility review in every free pavement assessment, so you know what you are dealing with before it shows up as a complaint.

Frequently Asked Questions

How many ADA parking spaces are required in Texas?

The count scales with total spaces: one accessible space for the first 25, two up to 50, three up to 75, four up to 100, then a slower sliding scale above that. At least one in every six accessible spaces, rounded up, must be van-accessible.

What are the ADA parking space dimensions?

A car-accessible stall is at least 96 inches wide with a 60-inch access aisle. A van-accessible stall is 132 inches wide with a 60-inch aisle, or 96 inches wide with a 96-inch aisle. Slope in any direction at the stall and aisle cannot exceed 1:48, roughly 2 percent.

Does restriping a parking lot trigger ADA upgrades in Texas?

Restriping an existing layout in its existing configuration is generally treated as maintenance. Changing the layout, resurfacing, or altering the accessible route can trigger a requirement to bring accessible elements up to current Texas Accessibility Standards.

How high do accessible parking signs have to be mounted?

The bottom of the sign must be at least 60 inches above the ground surface so it stays visible when a vehicle is parked in the space. Van-accessible spaces need an additional van-accessible designation, and Texas requires fine notice signage as well.
